BACKGROUND: Transtibial (TT) or tibial inlay (TI) techniques are commonly used for posterior cruciate ligament reconstruction (PCLR). However, the optimum method for PCLR after PCL injury remains debatable. Hypothesis/Purpose: The hypothesis was that TT and TI techniques would not show significant differences for all outcome measures. The purpose was to determine the biomechanical and clinical outcomes of TT and TI surgical techniques for PCLR. STUDY DESIGN: Meta-analysis; Level of evidence, 3...

Erik Nout, Maurice Y Mommaerts
CONTEXT: Cranioplasty is a frequently performed procedure that uses a variety of reconstruction materials and techniques. In this technical note, we present refinements of computer-aided design-computer-aided manufacturing inlay cranioplasty. OBJECTIVE, DESIGN, AND SETTING: In an attempt to decrease complications related to polyether-ether-ketone (PEEK) cranioplasty, we gradually made changes to implant design and cranioplasty techniques. These changes include under-contouring of the implant and the use of segmented plates for large defects, microplate fixation for small temporal defects, temporal shell implants to reconstruct the temporalis muscle, and perforations to facilitate the drainage of blood and cerebrospinal fluid and serve as fixation points...

OBJECTIVE: To investigate the longevity and reasons for failure of posterior cast Class II gold inlays and onlays among a group of Norwegian adults. The term inlay was used for both inlays and onlays. METHODS: A cohort of 138 patients regularly attending a general practice for check-up were examined in 2016. The patients had a total of 391 posterior gold inlays placed in the period 1970-2015. The inlays were categorized as successful, repaired or failed. Reasons for failure were classified as either "secondary caries", "fractures", "lost inlay" or "other"...

Takaaki Shinohara, Hitoshi Hirata
We describe a 59-year-old man who had nonunion of a right distal radius fracture after volar locking plate fixation. He underwent open reduction and internal fixation with a volar locking plate system for a dorsally displaced, unstable distal radius fracture at a previous hospital 5 months ago. Radiographs of the injured wrist showed nonunion of the distal radius with 1.5-mm ulnar minus variance. Radiographs of the unaffected wrist showed 3.5-mm ulnar plus variance. Intraoperative findings of surgical revision showed an unstable nonunion; thus, debridement of the nonunion, autogenous inlay bone grafting, and internal fixation using another type of volar locking plate system were performed...

Introduction Patients with low rectal cancer or anal cancer undergoing abdominoperineal excision (APE) benefit from extended surgery and the subsequent avoidance of surgical "waisting" at the level of the puborectalis muscle. The method of cylindrical APE was introduced by T. Holm and led to a reduction of intraoperative perforations and involvement of circumferential resection margins, and subsequently reduced the risk of local recurrence. The use of myocutaneous flaps reduces perineal wound complications, which occur in up to 60% of patients with primary closure of perineal defects, especially following neoadjuvant radiochemotherapy...

Mitchell R Gore
Background: Lateral sphenoid encephaloceles present a surgical challenge. These encephaloceles may be difficult to access given their lateral location and proximity to the neural and vascular structures of the sphenoid floor, pterygopalatine fossa, and lateral and superior sphenoid walls. Additionally, many patients have idiopathic intracranial hypertension, increasing the risk of recurrence. When untreated or undiscovered, these encephaloceles increase the risk of meningitis. Methods: All consecutive endoscopic repairs of lateral sphenoid encephaloceles by a single surgeon from 2012 to 2017 were analyzed for method of repair, complications, and recurrence rate...

Introduction: Isolated, neglected medial malleolus nonunion cases are a rare entity in orthopedic literature. All studies (except one) have described the use of compression screws (with or without plates) for medial malleolar nonunion management. In acute fractures, tension band wiring (TBW) has shown excellent results both in biomechanical and in clinical studies. On the contrary, it has seldom been used in nonunion or in neglected cases. Case Report: We describe a 6-month-old neglected medial malleolus gap nonunion case who presented with progressive pain and limp...

PURPOSE: Managing focal cartilage injuries in the middle-aged patient poses a challenge. Focal prosthetic inlay resurfacing has been proposed to be a bridge between biologics and conventional joint arthroplasty. Patient selection and accurate implant positioning is crucial to avoid increased contact pressure to the opposite cartilage surface. A customized femoral condyle implant for focal cartilage injuries was designed to precisely fit each patient's individual size and location of damage...

Aim CoCrMo alloys are contraindicated for sufferers from allergy. For these patients, uncemented and cemented prostheses made of non-allergenic titanium alloy are indicated. Knee prostheses machined from that alloy, however, may have poor tribological behaviour, especially in contact to UHMWPE inlays. Therefore, high-strength oxide ceramics may be especially suitable for knee replacement in allergy patients with mobile bearing prostheses. For adhesion to bone cement, the ceramic surface only exhibits mechanical retention spots that are less adequate than those with a textured metal surface...

Provisional restorations play an important role when providing indirect restorations. There are a number of materials and techniques available for their construction. Careful planning and construction can protect the prepared tooth surface, improve the periodontal condition and help plan for the definitive restoration. A good provisional restoration can save time, money and effort. Clinical relevance: Provisional restoration construction is an integral part of the indirect restorative process for inlays, onlays, crowns and bridges...

OBJECTIVES: Buccal mucosa grafts and fascio-cutaneous flaps are frequently used in long anterior urethral strictures (1). The inlay and onlay buccal mucosa grafts are easier to perform, do not need urethral mobilization and generally have good long-term results (2-4). In the present video, we present a case where we used a double buccal mucosa graft technique in a simultaneous penile and bulbar urethral stricture. MATERIALS AND METHODS: A 54 year-old male patient was submitted to appendectomy where a urethral catheter was used for two days in May 2015...
